Full textAbstract:
Ranking and Selection procedures have been designed to select the best system from a
number of alternatives, where the best system is defined by the given problem. The primary
focus of this thesis is on experiments where the data are from simulated systems. In simulation
ranking and selection procedures, four classes of comparison problems are typically
encountered. We focus on two of them: Bernoulli and multinomial selection. Therefore, we
wish to select the best system from a number of simulated alternatives where the best system
is defined as either the one with the largest probability of success (Bernoulli selection)
or the one with the greatest probability of being the best performer (multinomial selection).
We focus on procedures that are sequential and use an indifference-zone formulation
wherein the user specifies the smallest practical difference he wishes to detect between the
best system and other contenders.
We apply fully sequential procedures due to Kim and Nelson (2004) to Bernoulli data
for terminating simulations, employing common random numbers. We find that significant
savings in total observations can be realized for two to five systems when we wish to detect
small differences between competing systems. We also study the multinomial selection
problem. We offer a Monte Carlo simulation of the Bechhofer and Kulkarni (1984) MBK
multinomial procedure and provide extended tables of results. In addition, we introduce a
multi-factor extension of the MBK procedure. This procedure allows for multiple independent
factors of interest to be tested simultaneously from one data source (e.g., one person
will answer multiple independent surveys) with significant savings in total observations
compared to the factors being tested in independent experiments (each survey is run with
separate focus groups and results are combined after the experiment). Another multi-factor
multinomial procedure is also introduced, which is an extension to the MBG procedure due to Bechhofer and Goldsman (1985, 1986). This procedure performs better that any other
procedure to date for the multi-factor multinomial selection problem and should always be
used whenever table values for the truncation point are available.

In the agri-chain of cassava starch in Brazil, the supply of firms is through different governance structures. These structures range from the purchase via the spot market - without any contractual control over the production - to the hierarchy or vertical integration, structure in which the company is growing in own areas, with full control over the production. Between these two extremes were also identified other governance structures, which are called Hybrid arrangements that can approach the spot market or hierarchy. This essay aimed to identify the factors that influence the decisions of the paranaenses starch factories on the governance structures in buying - cassava supply in the state of Paraná. The specific objectives are: a) show if there is specifics that support the necessity to search for a particular organizational arrangement to the detriment of business through the spot market in the state of Paraná; b) analyze the factors that justify the choices of cassava starch factories for plural or singular forms in the state of Paraná; c) comparing the efficiency of the use or the combination of governance mechanisms in cassava starch factories in Paraná State, considering idleness as an index for the year 2014. The entire analysis of this essay is based on the theoretical assumptions of the New Institutional Economics (NIE), especially in the Transaction Cost Economics (TCE). In this essay the explanatory method was the most appropriate, once for this it sought to identify the determining factors for the occurrence of the phenomena observed: i) coexistence of plural forms of governance to coordinate the purchase of cassava by starch factories in Brazil and in the state of Paraná. This research method more approach the scientific knowledge to the real world as it explains the reason and why the facts. In the case of cassava, the characteristics of transactions - temporal and locational characteristics, as well as uncertainty and frequency – were not relevant for the choice of governance structures, on the contrary to what literature indicates. Even considering these characteristics, in Brazil and in the state of Paraná was prevailing the coordination by the spot market. The results also indicated the existence of a plurality of transactions in many levels - with different agents, and similar agents in a single transaction - since the combination of different governance structures can reduce transaction costs and even increase the efficiency of industry here measured by the reduction of industrial idleness.
Na cadeia agroindustrial da fécula de mandioca no Brasil, o suprimento das firmas se dá por meio de diferentes estruturas de governança que variam desde a compra via mercado spot - sem qualquer controle contratual sobre a produção – até a hierarquia ou integração vertical, estrutura na qual a firma faz o cultivo em áreas próprias, com total controle sobre a produção. Entre estes dois extremos foram identificadas ainda outras estruturas de governança, as quais se denominam por arranjos híbridos, que podem se aproximar do mercado spot ou da hierarquia. Esta dissertação teve como objetivo identificar os fatores que influenciam a escolha as decisões das fecularias paranaenses sobre as estruturas de governança na compra de mandioca no estado do Paraná. Os objetivos específicos são: a) Apresentar as estruturas de governança prevalecentes nas fecularias brasileiras; b) Mostrar se há especificidades que fundamentem a necessidade da busca de um determinado arranjo organizacional em detrimento de negócios por meio do mercado spot no estado do Paraná; c) analisar os fatores que justificam as opções das fecularias por formas plurais ou singulares no estado do Paraná; d) comparar a eficiência do uso ou da combinação dos mecanismos de governança na indústria paranaense de fécula de mandioca, considerando a ociosidade como indicador para o ano de 2014. Toda a análise desta dissertação tem como base os pressupostos teóricos da Nova Economia Institucional (NEI), especialmente na Economia dos Custos de Transação (ECT). Nesta dissertação o método explicativo foi o mais indicado, uma vez que por este buscou-se identificar os fatores determinantes para a ocorrência dos fenômenos observados: i) coexistência de formas plurais de governança para coordenar a compra de mandioca pelas fecularias no Brasil e no estado do Paraná. Este método de pesquisa mais aproxima o conhecimento científico com o mundo real uma vez que explica a razão e o porquê dos fatos. No caso da mandioca, as características das transações – especificidades temporal e locacional, bem como incerteza e frequência – não fora relevantes para a escolha das estruturas de governança, ao contrário do que se aponta a literatura. Mesmo considerando estas características, no Brasil, bem como no estado do Paraná foi prevalecente a coordenação pelo mercado spot. Os resultados indicaram ainda a existência da pluralidade nas transações em diversos níveis – com diferentes agentes, com agentes similares e em uma mesma transação - uma vez que a combinação de diferentes estruturas de governança podem diminuir custos de transação e até mesmo aumentar a eficiência da indústria, aqui mensurado pela diminuição de ociosidade industrial.

Relatório de Estágio apresentado para cumprimento dos requisitos necessários à obtenção do grau de Mestre em JornalismoEste relatório tem como objectivo dar a conhecer a forma como os sites das rádios portuguesas ainda não estão totalmente adaptados à Internet e não aproveitam na totalidade todas as ferramentas hipermédias que têm à sua disposição. O exemplo usado é o da rádio pública Antena 1, onde o estágio curricular de Mestrado aconteceu. Este site ainda funciona principalmente como depósito de informação e não como um meio complementar e bastante útil para aproximar os ouvintes da Rádio e tornar ainda mais evidente a sensação de intimidade que se cria entre uma rádio e o sue público. A Internet, através de ferramentas interactivas, que permitem aos utilizadores darem opiniões, comentar artigos e mesmo montar o seu bloco noticioso, de acordo com a sua preferência, cria a sensação de proximidade e fazem-nos sentir participantes da sociedade. Através da exposição das principais características quer da Rádio, quer da Internet e de uma análise genérica do panorama das principais rádios de informação portuguesas chega-se ao caso da Antena 1, onde através do estudo das notícias colocadas online se demonstra que nenhuma delas é diferente daquelas que dadas na edição tradicional, o que transforma o site num depósito de notícias e falha completamente o objectivo de complementaridade entre Rádio e Internet, que, como será demonstrado, é possível e conveniente num futuro próximo.

Full textAbstract:
The problem to be investigated in this study focuses on the development of a method to improve the quality of the data contained in the academic student records component of a data warehouse (DW) in a higher education setting. A DW should contain high-quality data and be considered a successful implementation by the stakeholders of the system. Such a system will allow administrators at higher education institutions to be able to make sound decisions for their college or university. A questionnaire was made available to information technology specialists and managerial end-users who worked in higher education institutions. These potential respondents were contacted by-mail and provided a link to a web-site that allowed them participants to access the questionnaire.
The data collected from the questionnaire responses was analyzed by using a chi square analysis and an analysis of variance. DW quality was used as the dependent variable in this study. Whether or not a design methodology was used in the development of the DW or other on-line analytical processing (OLAP) data architecture, the extent of metadata use during the development of the DW or other OLAP data architecture, whether or not data marts were developed before the development of the DW or other OLAP architecture, and the amount of collaboration used in the development of the DW or other OLAP architecture were used as independent variables in this study. The researcher identified positive relationships that existed between quality variables and design constructs. These constructs were then used to build a model for building a DW that could be used for higher education applications. This model focused on the academic student records applications. After analysis of the responses from the questionnaire, it was determined that the use of Meta data and end-user involvement had a positive relationship to obtaining high-quality data in a DW. Based on these results a model using a star-schema and a modification of the Zachman Framework was developed. A suggestion as to the organizational structure that can lead to a successful DW implementation was also suggested. This structure allows for increased control of the project during its development and implementation by the use of metadata. The ultimate goal of the researcher in this study was to build a model for a DW in higher education that can improve decision-making performance of administrators at higher education institutions.

Mestrado em Ciências EmpresariaisO fenómeno da internet veio revolucionar os padrões tradicionais de divulgação e tratamento de informação nas empresas, permitindo assim, um contato mais próximo com os seus investidores. Como tal, surgem novas oportunidades para as empresas, novas formas de comunicar, permitindo usufruir de um canal de comunicação poderoso a baixo custo. Desta forma, cada empresa tende a diferenciar-se de forma a atrair investidores. Considerando as oportunidades, foi elaborado um índice com uma listagem de itens, verificando quais as informações corporativas presentes nos sites institucionais. E como tal, surgem variáveis determinantes no nível de IFR na divulgação, nomeadamente tamanho, rentabilidade, indústria tecnológica, free float, risco sistemático, empresas cotadas em mercados estrangeiros e a corporate governance. O presente trabalho, pretende analisar o impacto destas diferentes variáveis no nível de divulgação de informação corporativa, utilizando o conjunto de empresas do índice FTSE100 indicadas no mercado de capitais inglês. No desenvolvimento do estudo, os dados foram obtidos através da observação direta e análise descritiva e intuitiva. Desta forma os resultados obtidos, demostram que as empresas cotadas no FTSE100 apostam na divulgação de informação e que as variáveis como a dimensão da empresa e de corporate governance têm impacto no nível de divulgação através da internet.
The internet phenomenon has deeply transformed the traditional way of processing the information and the way of communicating with investors. The internet allows new opportunities of business, new ways of communicating, being a powerful communication channel at a low cost. Each company tends to differentiate themselves in order to attract investors. Therefore, in order to analyze the level of IFR in a sample of UK firms, we constitute an index for a sample of listed UK firm based on a list of items from the literature. The index includes two major groups of itens: (1) one with the contents of the information disclosed in the site and (2) the other regarding the presentation of the information in the site. Additionally, we also verify if variables such as firm size, profitability, technology industry, free float, systematic risk, companies listed on overseas markets and the corporate governance mechanisms has any impact on the level of IFR. Our analysis is based on the set of companies of the FTSE 100 index. Data were obtained through direct observation of the different institutional sites. The results show that companies listed on FTSE100 invest on the disclosure via the internet to investors and that variables as the size, profitability and corporate governance mechanisms have an influence in the level of IFR of FTSE 100´s firms.

Pretende-se com esta investigação avaliar se as notícias que foram divulgadas no período oficial de campanhas seguem algum padrão ou tendência em relação ao conteúdo, imagem e extensão da informação divulgada, assim como na abordagem aos partidos e candidatos envolventes nesta “competição”. Para alcançar respostas avaliou-se as tiragens de seis publicações nacionais durante o período oficial das campanhas eleitorais, de modo a compreender se existe um consenso ou caso contrário se não se verifica nenhum padrão. Atualmente, os media assumem-se como uma das ferramentas utilizadas pelos eleitores para se informarem e formularem as suas decisões eleitorais. Neste trabalho não será possível verificar o nível de influência dos meios de comunicação nas decisões eleitorais, no entanto, interessa-nos compreender se os mass media seguem a mesma conduta na seleção de informação (agenda-setting) para perceber se existe ou não uma polivalência nos conteúdos que são divulgados aos eleitores.

Full textAbstract:
We propose using statistical regular pavings (SRPs) as an efficient and adaptive statistical data structure for processing massive, multi-dimensional data. A regular paving (RP) is an ordered binary tree that recursively bisects a box in $\Rz^{d}$ along the first widest side. An SRP is extended from an RP by allowing mutable caches of recursively computable statistics of the data. In this study we use SRPs for two major applications: estimating histogram densities and summarising large spatio-temporal datasets.
The SRP histograms produced are $L_1$-consistent density estimators driven by a randomised priority queue that adaptively grows the SRP tree, and formalised as a Markov chain over the space of SRPs. A way to select an estimate is to run a Markov chain over the space of SRP trees, also initialised by the randomised priority queue, but here the SRP tree either shrinks or grows adaptively through pruning or splitting operations. The stationary distribution of the Markov chain is then the posterior distribution over the space of all possible histograms. We then take advantage of the recursive nature of SRPs to make computationally efficient arithmetic averages, and take the average of the states sampled from the stationary distribution to obtain the posterior mean histogram estimate.
We also show that SRPs are capable of summarizing large datasets by working with a dataset containing high frequency aircraft position information. Recursively computable statistics can be stored for variable-sized regions of airspace. The regions themselves can be created automatically to reflect the varying density of aircraft observations, dedicating more computational resources and providing more detailed information in areas with more air traffic. In particular, SRPs are able to very quickly aggregate or separate data with different characteristics so that data describing individual aircraft or collected using different technologies (reflecting different levels of precision) can be stored separately and yet also very quickly combined using standard arithmetic operations.

Full textAbstract:
O presente trabalho trata da recepção crítica, no Brasil e na Espanha, de três obras do escritor francês André Malraux - La Condition humaine, L’Espoir e Antimémoires. A análise fundamenta-se em alguns princípios teóricos da Literatura Comparada e utiliza noções básicas da Estética da Recepção, da Crítica Literária e da Tradução. O estudo reúne e analisa textos publicados em jornais e revistas, literários e jornalísticos, no período compreendido entre 1933, ano da publicação de La Condition humaine e 2001, ano do centenário de nascimento do escritor. Compõem também o corpus alguns textos produzidos em momentos de especial interesse da biografia do autor (participação na Guerra Civil Espanhola, visita ao Brasil, falecimento e transferência das cinzas para o Panthéon parisiense). Além da pesquisa em jornais e revistas, a Internet foi também uma fonte importante de informações. O estudo mostra que Malraux despertou inicialmente a atenção dos críticos e leitores com seus romances ideológicos, participativos e até revolucionários, adequados ao horizonte de expectativa dos leitores da época, dominada então pela política e pela ideologia, assim como revela que o interesse das gerações pós-guerra por Malraux se justifica pelo valor estético de suas obras. A pesquisa evidencia uma diferença significativa entre o Brasil e a Espanha no que se refere, de um lado, ao número de edições das obras traduzidas e, de outro, ao momento em que ocorreram as traduções. Na Espanha, a tradução começou somente a partir da década de 60, enquanto que no Brasil, de 1933 a 1973, registrou-se uma edição em português a cada década, fato que se repetiu na década de 90 e em 2001. Conta-se um total de 36 edições na Espanha e de apenas 7 edições no Brasil das três obras estudadas. Estes dados são apresentados em gráficos nos anexos da tese, assim como quatro tabelas com as máximas malrucianas, as edições das traduções brasileiras e espanholas das obras, a malruciana brasileira e a malruciana espanhola. Nos anexos, pode-se ler também o discurso pronunciado por Malraux em Madri, no dia 7 de julho de 1937 e, a título de ilustração, seguem-se fotos de Barcelona durante a Guerra Civil, com referências aos locais feitas por Malraux em L’Espoir. A bibliografia comporta, em diferentes itens, referências a textos das críticas brasileira e espanhola, a textos encontrados na Internet e às obras consultadas para a fundamentação teórica da pesquisa.

Previous issue date: 2015The research reported on this dissertation focused on a significant pedagogical chance started on 2011-2012 period, in Rio Grande do Sul state scenario: the State Secretary of Education Proposal to Polytechnic High School implementation. In this scenario, the research, as a pedagogical principle, occupy, from a theoretical point of view, privileged space. However, it is necessary to evaluate how students are located in this reality and how the Integrated Seminar discipline addresses the research. Therefore, on the research, were sought answers to the following question: How Polytechnic High School students realize the research developed under public schools in Porto Alegre on the Integrated Seminar discipline from Natural Sciences area? The assumptions underpinning this research are grounded on the conceptions of polytechnic, the principles of curriculum restructuring in Rio Grande do Sul and in the investigation as a pedagogical principle in High School. The data were collected through recorded interviews with focus groups of students from eight schools of Porto Alegre macrozones, whose answers were analyzed through Discursive Textual Analysis – ATD, in order to perceive the understanding of students in relation to the Polytechnic High School, specially the research experiences. Can be stated as main conclusions that the texts that support the proposal of the Polytechnic High School are consistent from a theoretical point of view and the research as a pedagogical principle has highlight by its importance on the students development of citizenship and autonomy. However, it is observed, through the testimony of students, that in the eight schools investigated, the assumptions of polytechnic and didactic-methodological actions to achieve its objectives have not been fully appropriated by the teachers yet. Also, in the view of the students interviewed, is quite poor the pedagogical support of official agencies to teachers regarding the implementation of the proposal. In relation to the researches conducted in the studied schools in the scope of Integration Seminar discipline, based on the vision of the students, it appears that the actions are quite distant than those related by the authors that deal with research as pedagogical and methodological principle.
A pesquisa relatada nesta dissertação abordou uma significativa mudança pedagógica iniciada no período de 2011-2012, no cenário do Estado do Rio Grande do Sul: a Proposta da Secretaria de Educação do Estado, para a implantação do Ensino Médio Politécnico. Neste cenário, a pesquisa, como princípio pedagógico, ocupa, do ponto de vista teórico, espaço privilegiado. No entanto, é necessário avaliar como os estudantes se situam nessa realidade e como a disciplina de Seminário Integrado aborda a pesquisa. Por isso, na investigação, buscaram-se respostas para o seguinte questionamento: De que modo os estudantes do ensino médio politécnico percebem a pesquisa desenvolvida no âmbito de escolas públicas de Porto Alegre na disciplina Seminário Integrado da área de Ciências da Natureza? Os pressupostos desta pesquisa alicerçam-se nas concepções sobre Politecnia, nos princípios da reestruturação curricular no Rio Grande do Sul e na pesquisa como princípio pedagógico no Ensino Médio.A coleta de dados ocorreu por meio entrevistas gravadas com grupos focais de estudantes de oito escolas das macrozonas de Porto Alegre, cujas respostas foram analisadas por meio da Análise Textual Discursiva – ATD, com vistas a compreender os entendimentos dos estudantes em relação ao Ensino Médio Politécnico, em especial, as vivências de pesquisa. Como principais conclusões, pode-se afirmar que os textos que embasam a proposta do Ensino Médio Politécnico mostram-se consistentes do ponto de vista teórico e a pesquisa como princípio pedagógico tem destaque pela sua importância no desenvolvimento da cidadania e autonomia dos estudantes. No entanto, observa-se, por meio dos depoimentos dos estudantes, que nas oito escolas investigadas, os pressupostos sobre politecnia e as ações didático-metodológicas para a consecução dos seus objetivos não foram ainda devidamente apropriados pelos professores. Também, na ótica dos estudantes entrevistados, é bastante deficiente o apoio pedagógico dos órgãos oficiais aos professores em relação à execução da proposta. Em relação às pesquisas realizadas nas escolas estudadas no âmbito da disciplina Seminário Integrador, com base na visão dos estudantes, depreende-se que as ações são bastante distantes do que referem os autores que tratam sobre a pesquisa como princípio pedagógico e metodológico.

Wang, Fan. "Localities of global modernism : Fei Ming, Mu Dan and Wang Zengqi." HKBU Institutional Repository, 2020. https://repository.hkbu.edu.hk/etd_oa/760.
Full textAbstract:
This thesis seeks to map out the development of literary modernism in the 1930s and 1980s People's Republic of China (PRC). Despite the long temporal halt, these two periods are innately and historically related to each other. Much as Chinese literary modernism was a literary legacy of Western modernism, its decades-long development provided it with the conditions for a second life. When it reemerged in the 1980s, it bore unique national characteristics that, in turn, enriched the realm of global modernism. In short, the distinct historical and national context of the twentieth century China dictated that Chinese literary modernism could not be a mechanical reproduction of its Western counterpart. The importation and translation of Western modernist creative and critical works, together with the modernist practices of modern Chinese intellectuals, contributed to the formation and rise of modernist literature in the 1930s, as well as its revival in the 1980s PRC. Structurally, this thesis identifies three localities of global modernism in the works and literary theory of Fei Ming, Mu Dan, and Wang Zengqi. It argues that these writers' modernist practices and distinct writing styles not only represented the characteristics of Chinese literary modernism, but also added diversities to modernist literature in the global context. Methodologically, I pair the Chinese modernists with their Western counterparts, including Virginia Woolf and T.S. Eliot. This comparison helps to find similarities between modernist works across time and place, and to identify the unique features of Chinese literary modernism. In practice, when studying the three modernists' first encounters with literary modernism in Republican China, as well as their respective experience in the PRC, I seek to (i) present three modes of initiation of literary modernism at the beginning of the twentieth century; (ii) trace the development of literary modernism both in the republican era and its revival in the PRC; (iii) show the process of Chinese literary modernism growing its distinct characteristics and evidence its second life. In short, Chinese modernists' participation in the building of global modernism and their contributions to the enrichment of literary modernism in the global context are two foci of my thesis. In the final analysis, this thesis engages research on Chinese literary postmodernism. No matter the literary movement's status in the PRC, then and now, how and why it differs from the development of postmodernism in Western literature and culture are valuable research questions.

Esta tesis analiza y compara el uso de espacio en las etiquetas de las tecnologias basadas en ellas para garantizar su escalabilidad. La aplicabilidad de las técnicas existentes y los estudios que se pueden utilizar para superar o reducir los problemas de escalabilidad de la etiqueta son evaluados. Además, esta tesis propone un ILP para calcular el óptimo rendimiento de las technologias basadas en STP y las compara con las basadas en etiquetas para ser capaz de determinar, dada una específica situacion, que technologia utilizar.Ethernet is starting to move from Local area networks to carrier networks. Nevertheless as the requirements of carrier networks are more demanding, the technology needs to be enhanced. Schemes designed for improving Ethernet to match carrier requirements can be categorized in two classes. The first class improves Ethernet control components only (STP based technologies), and the second class improves both Ethernet control and forwarding components (label based forwarding technologies). This thesis analyzes and compares label space usage for the label based forwarding technologies to ensure their scalability. The applicability of existing techniques and studies that can be used to overcome or reduce label scalability issues is evaluated. Additionally this thesis proposes an ILP to calculate optimal performance of STP based approaches and compares them with label based forwarding technologies to be able to determine, given a specific scenario, which approach to use.

Full textAbstract:
Ecological modelling problems have characteristics both featured in other modelling fields and specific ones, hence, methods developed and tested in other research areas may not be suitable for modelling ecological problems or may perform poorly when used on ecological data. This thesis identifies issues associated with the techniques typically used for solving ecological problems and develops new generic methods for decision support, especially suitable for ecological data modelling, which are characterised by: (1) adaptive learning, (2) knowledge discovery and (3) accurate prediction. These new methods have been successfully applied to challenging real world ecological problems. Despite the fact that the number of possible applications of computational intelligence methods in ecology is vast, this thesis primarily concentrates on two problems: (1) species establishment prediction and (2) environmental monitoring. Our review of recent papers suggests that multi-layer perceptron networks trained using the backpropagation algorithm are most widely used of all artificial neural networks for forecasting pest insect invasions. While the multi-layer perceptron networks are appropriate for modelling complex nonlinear relationships, they have rather limited exploratory capabilities and are difficult to adapt to dynamically changing data. In this thesis an approach that addresses these limitations is proposed. We found that environmental monitoring applications could benefit from having an intelligent taste recognition system possibly embedded in an autonomous robot. Hence, this thesis reviews the current knowledge on taste recognition and proposes a biologically inspired artificial model of taste recognition based on biologically plausible spiking neurons. The model is dynamic and is capable of learning new tastants as they become available. Furthermore, the model builds a knowledge base that can be extracted during or after the learning process in form of IF-THEN fuzzy rules. It also comprises a layer that simulates the influence of taste receptor cells on the activity of their adjacent cells. These features increase the biological relevance of the model compared to other current taste recognition models. The proposed model was implemented in software on a single personal computer and in hardware on an Altera FPGA chip. Both implementations were applied to two real-world taste datasets.In addition, for the first time the applicability of transductive reasoning for forecasting the establishment potential of pest insects into new locations was investigated. For this purpose four types of predictive models, built using inductive and transductive reasoning, were used for predicting the distributions of three pest insects. The models were evaluated in terms of their predictive accuracy and their ability to discover patterns in the modelling data. The results obtained indicate that evolving connectionist systems can be successfully used for building predictive distribution models and environmental monitoring systems. The features available in the proposed dynamic systems, such as on-line learning and knowledge discovery, are needed to improve our knowledge of the species distributions. This work laid down the foundation for a number of interesting future projects in the field of ecological modelling, robotics, pervasive computing and pattern recognition that can be undertaken separately or in sequence.

Full textAbstract:
This thesis looks at a period of Northumbrian history when the king was a part Irish, Iona trained scholar. Some have suggested that Aldfrith was assisted to the kingship by the northern victors of the battle of Nechtansmere. It examines processes in the late seventh century to try to identify changes that might have happened during the reign of this king. The study begins with a wide overview of previous research to establish a basis from which to look for processes and change and also examines the sources available to us, written and archaeological. It then looks at the kingdoms to the north and west and at Aldfrith and the period of his reign. The suggestion is made that Aldfrith acted, with the Church, to cult saints that were Northumbrian and Romanist, as opposed to other options that might have been available. It proposes that the Northumbrians rejected opportunities to develop links with the north and west that may have been open to them. The following chapters then examine processes underway in Northumbria in three general areas; in the use of power, in society, and in the economy. It concludes that although many processes continued as before, these sped up and in certain areas such as the production of coins, and the consequential development of trade, it was a period of innovation. There is no evidence of a focus to the north and west during Aldfrith's reign and this has implications for how Aldfrith got to the throne, suggesting that it was with the support of the Northumbrian elite and not through the military strength of the Dál Riata or the Picts. The evidence is that Northumbria increasingly looked south for its influences and is prepared to absorb and implement processes and approaches from southern England, Gaul and Rome.

Conselho Nacional de Desenvolvimento Científico e TecnológicoSunflower is an alternative specie to the system of no-tillage and crop rotation. His inclusion in this system provides soil improvements and interruption on cycle of pests and diseases, which are responsible for losses of productivity of the mainly sown crops. In addition to these benefits this specie has characteristics of increased tolerance to drought than traditional crops such as soybean and corn, maintaining satisfactory yields even in dry years considereds. For inclusion in the rotation and maintaining satisfactory yields the knowledge of the best sowing dates is necessary. As the weather has interannual variability, the risk analysis for the sowing dates is required, through a study of probability with a long series of weather data for better definition. This study aims to determine the sowing date of sunflower in which lower severity of alternaria and septoria leaf spots in the RS Central Region occurs. For it has adapted and calibrated an algorithm providing a forecasting system diseases, based on data from leaf wetness duration, air temperature during the leaf wetness period and rain, calculating the accumulated severity values (VSCA) throughout the cycle. In this adaptation and calibration data from six experiments performed at the Department of Plant Science since 2007. Hourly values of weather data from 1968 to 2011 was estimated from the default readings, and use this algorithm were simulated for 14 different dates of sowing spaced in 15 days, beginning on August 1 and ending on February 16 of each year. Due to the interannual variability of ENSO and their influence on weather conditions, crop seasons years was apart in Neutral, La Niña and El Niño. The data generated from the analysis of variance and the means of Scott- Knott test at 5% probability of error was taken. In addition, the VSCA were subjected to analysis of probability distribution, verifying that the Weibull, lognormal and normal distributions has the best represent the distribution of values of severity of leaf spots on sunflower, both for the entire cycle and for the subperiods emergency-end of anthesis and early reproductive-final stage of anthesis sunflower. It was also found that the period between early February and late April is more favorable to leaf spots, while sowing dates from August 1 to October 16, resulting in lower severity values, differing significantly from later sowings. In El Niño years suffer the greatest severities of disease, followed by La Niña years, and finally with the lowest values of VSCA for Neutrals years.
O girassol é uma espécie alternativa para o sistema de plantio direto e rotação de culturas. Sua inserção neste sistema proporciona melhorias edáficas e interrupção do ciclo de pragas e doenças causadoras de perdas de produtividade nas culturas agrícolas mais semeadas. Além destes benefícios, esta espécie possui características de maior tolerância ao déficit hídrico do que culturas tradicionais como a soja e o milho, mantendo produtividades satisfatórias mesmo em anos considerados secos. Para a sua inclusão no sistema de rotação e manutenção de produtividades satisfatórias é necessário o conhecimento das melhores datas semeadura. Como as condições meteorológicas tem variabilidade interanual, é necessária a análise de risco para uma mesma data de semeadura, através de um estudo de probabilidade com uma série longa de dados meteorológicos para sua melhor definição. Este trabalho objetiva determinar a data de semeadura do girassol na qual ocorre menor severidade das manchas foliares de alternária e septória, na Região Central do RS. Para isso adaptou-se e calibrou-se um algoritmo provendo um sistema de previsão de doenças, baseado em dados de duração do molhamento foliar, temperatura do ar durante o período de molhamento foliar, e chuva, obtendo-se os valores de severidade calculada acumulados (VSCA) durante todo o ciclo. Nesta adaptação e calibração utilizaram-se dados de seis experimentos realizados no Departamento de Fitotecnia desde o ano de 2007. Os dados meteorológicos estimados para valores horários de 1968 até 2011, a partir das leituras padrão, e a utilização deste algoritmo, foram simuladas para 14 diferentes datas de semeadura espaçadas em 15 dias, iniciando em 01 de agosto e finalizando em 16 de fevereiro de cada ano. Devido à variabilidade interanual do fenômeno ENOS e sua influência sobre as condições meteorológicas, os anos separados em Neutros, La Niña e El Niño. A partir dos dados gerados foi feita a análise de variância e o teste de médias de Scott-Knott a 5% de probabilidade de erro. Além disso, os VSCA obtidos foram submetidos a análise de distribuição de probabilidade, verificando-se que as distribuições Weibull, lognormal e normal representam melhor a distribuição dos valores de severidade máxima das manchas foliares no girassol, tanto para o ciclo completo quanto para os subperíodos emergência-final da antese e início da fase reprodutiva-final da antese do girassol. Verificou-se ainda que o período entre o início de fevereiro e o final de abril é mais favorável às manchas foliares, enquanto que as datas de semeadura de 01 de agosto a 16 de outubro resultam nos menores valores de severidade, diferindo significativamente das semeaduras posteriores. Em anos El Niño ocorrem as maiores severidades das doenças, seguido pelos anos de La Niña, e finalmente com os menores valores de VSCA para os anos Neutros.

Driven by a social need, the managers of an experimental farm belonging to the Agricultural Science Center at an institution of higher education raised concerns about ongoing support and maintenance of the farm. During the investigation process, the difficulty of filling staff positions for agricultural operations assistants was among the managers’ concerns. The reorganization of the workforce at a public institution is subject to public tenders, protocols and resolutions established by state law, university statute and internal regulations. The qualifications or knowledge contained in the professional profile description (personal competencies for the function) for an agricultural operations assistant established by the institution allow for explicit descriptions which fail to capture the reality of the work. Therefore, the aim of this thesis was to systematize the creation of work competencies for the position of an agricultural operations assistant from the perspective of ergonomic activity in order to improve the performance of the experimental farm. For the study of work and worker competencies unique to this context, an Ergonomic Work Analysis (EWA) research protocol was used, a methodology appropriate for ergonomic activity interventions. The organization of work at the experimental farm allows for flexibility in maneuvers that favor the use and evolution of competencies depending on the sector and individual initiative. The management model that establishes discretionary power and knowledge gained by operations assistant, are unique aspects of the determinants of the labor organization studied. As an experimental farm, the research, independent of any area it advances, uses new technologies and with this, the operational competencies are understood as factors inherent in the work, in the form of actions of the operations assistant, based on the characteristic of the organization (experimental farm - agricultural unit for research and teaching).
A partir de uma demanda social oriunda dos gestores da fazenda experimental pertencente ao Centro de Ciências Agrárias, vinculado a uma Instituição de Ensino Superior, revelou-se a preocupação com a sustentação e manutenção da fazenda. No decorrer do processo de investigação da demanda, constatou-se, entre as preocupações dos gestores, a dificuldade de ingresso de servidores e fixação dos mesmos nos cargos de auxiliar operacional agropecuário. A recomposição do quadro funcional pertencente a uma instituição pública está condicionado a concursos, protocolos e resoluções estabelecidos por leis estaduais, estatuto da universidade e regimentos internos. A qualificação ou saber do auxiliar operacional contidos na descrição do perfil profissiográfico estabelecidos pela instituição (competências pessoais para a função) possibilita descrições explícitas e lacunárias da realidade do trabalho. Assim sendo, o objetivo dessa tese foi sistematizar a construção das competências laborais do auxiliar operacional sob a perspectiva da ergonomia da atividade, visando contribuir para a melhoria do desempenho de uma fazenda experimental de Instituição de Ensino Superior. Para estudos sobre o trabalho e as competências do trabalhador, singulares ao contexto no qual está inserido, utilizou-se como protocolo de pesquisa a metodologia própria de intervenção da ergonomia da atividade, que é a Análise Ergonômica do Trabalho (AET). A organização do trabalho na fazenda experimental, possibilita margens de manobras que favorecem de modo diferenciado a utilização e evolução das competências, dependendo do setor e da iniciativa individual. O modelo de gestão que estabelece o poder discricionário e os saberes apreendidos pelo auxiliar operacional, são aspectos singulares dos determinantes da organização de trabalho estudada. Por ser uma fazenda experimental, a pesquisa, independente de qualquer área que ela avança, se utiliza de novas tecnologias e com isso, as competências operacionais, estão compreendidas aos fatores inerentes ao trabalho, na forma de ações do auxiliar operacional, condicionados sob a característica da organização (fazenda experimental - unidade agrícola de pesquisa e ensino).

The present theoretical-reflexive and empirical effort fits within the context of media reception studies and aims to understand the Angolan political-mediatic setting from the perspective of the subject-recipient supported by the Habermasian concept of the public sphere. This dissertation sought to move away from a view of a presumptive receiver, conjecturing possible interpretations for the media products, listening to the real receivers and knowing the true appropriation / positioning. The central hypothesis is that the Angolan families have a real and critical diagnosis of the surrounding situation from Telejornal (main news service of the country) but can not reach a libertarian conclusion. For the theoretical-methodological support, we have contributions from Jurgen Habermas, Stuart Hall, Raymond Williams, Boaventura de Sousa Santos, Laurence Bardin, Ricardo Soares de Oliveira, Jesus Martin-Barbero and Nilda Jacks. The research method used is the Family Mediation Technic that involves ethnography, television reception and in-depth Interview. The main result is that there is a production of sense capable of forming critical public spheres, but this does not happen due to the existence of fences - to a party-state and to the Cultural (patriarchal) fence. It is an empirical research that was carried out in the city of Luanda - capital of the Republic of Angola.
O presente esforço teórico-reflexivo e empírico enquadra-se no contexto dos estudos de recepção midiática e objetiva compreender o cenário político-midiático angolano sob a perspectiva do sujeito-receptor amparados pelo conceito habermasiano de esfera pública. Esta dissertação buscou sair de uma visão de um receptor pressuposto, conjecturando possíveis interpretações para os produtos midiáticos, escutando os receptores reais e conhecendo a verdadeira apropriação/posicionamento. A hipótese central é a de que as famílias angolanas têm a partir do Telejornal (principal serviço noticioso do país) um diagnóstico real e crítico da situação que vivem mas não conseguem chegar a uma conclusão libertária. Para o suporte teórico-metodológico, contamos com aportes de Jurgen Habermas, Stuart Hall, Raymond Williams, Boaventura de Sousa Santos, Laurence Bardin, Ricardo Soares de Oliveira, Jesus Martin-Barbero e Nilda Jacks. O método de pesquisa empreendido é a Técnica de Mediação Familiar que envolve etnografia, recepção televisiva e Entrevista em profundidade. O principal resultado é que existe produção de sentido capaz de formação de esferas públicas críticas, porém, isso não ocorre devido a existência de cercas- a cerca partido-Estado e a cerca Cultural (patriarcal). É uma pesquisa empírica que foi realizada na cidade de Luanda -capital da República de Angola.

Full textAbstract:
Dieser Artikel beschäftigt sich mit dem Modell der Budgetmitbestimmung in Porto Alegre. Aus dieser konkreten staatlichen Initiative, die die Zivilgesellschaft in einen sich öffnenden Staat einbindet, können Lehren für soziale Innovationen in Europa gezogen werden. Im Zuge des Widerstands gegen die Militärdiktatur bildeten sich Volksbewegungen, die gleichermaßen Staat und Kapital kritisierten. Diese herrschaftskritische Interpretation von Stadtteilbewegungen machte im Laufe der 1980er Jahre einer liberalen Interpretation Platz. In Verdrehung der Gramscianischen Intention wird Zivilgesellschaft zunehmend als die autonome Organisation nichtstaatlicher Organisationen begriffen. Damit wurden nicht nur zentrale Einsichten der marxistischen Staatstheorie über Bord geworfen, sondern gleichzeitig auch den liberalen Reformen des Staatsabbaus Vorschub geleistet. Lokalen Initiativen werden auf diese Weise fehl interpretiert, und ihr innovatives Potential wird nicht ausgeschöpft. Eine detaillierte Analyse der konkreten Stadtteilbewegungen in Brasilien hilft deshalb, ein klareres Verständnis von Staat und Gesellschaft zu gewinnen. Die Volksbewegungen forderten seit den 1970er Jahren sowohl materielle Verbesserungen in den bis dahin vernachlässigten Armenvierteln als auch weitergehende demokratische Mitspracherechte. Es entstand eine starke politische Bewegung, bestehend aus den erneut zugelassenen politischen Parteien und den schon gut vernetzten politischen Bewegungen. Das führte dazu, dass alltägliche Probleme der Bevölkerung in öffentliche Anliegen und daher in Forderungen an den Staat transformiert wurden. 1989 übernahm die Arbeiterpartei die Macht in Porto Alegre und begann die Demokratisierung der Lokalpolitik via Budgetmitbestimmung. Diese soziale Innovation des Regierens ist weltweit bekannt geworden. Wir beabsichtigen in diesem Artikel nicht nur eine Darstellung dieses Bürgerbeteiligungsmodells, sondern versuchen auch eine alternative Interpretation dieser politischen Strategie. Anders als in der konventionellen Theorie von Öffentlichkeit als Sphäre, die unabhängig von Markt und Staat existiert (Habermas) oder Zugängen, die auf Formen der Governance durch die Zivilgesellschaft setzen, gehen wir davon aus, dass nachhaltige soziale Innovation nur in einer neuen Form von Staatlichkeit bestand haben. Der Staat bleibt nämlich weiterhin der Knotenpunkt politischer Macht und Ansatzpunkt von Veränderungen, die über den Kapitalismus hinausgehen. Die Einbindung der Bevölkerung eröffnet Raum für das Experimentieren mit neuen Formen der Selbstverwaltung, die das Bürokratiemodell zu überwinden und einen offenen und öffentlichen Staat zu schaffen helfen.

Procedimentos de extração baseados nos princípios da química verde tem sido desenvolvidos desde 1990, com a miniaturização tendo um papel importante. A combinação da técnica extração sólido-líquido com partição em baixa temperatura (SLE/LTP) e a microextração líquido-líquido dispersiva com solvente de baixa densidade (LDS/DLLME), juntamente com a cromatografia gasosa com detector por captura de elétrons (GC/ECD) foi utilizada para a determinação de 2 agrotóxicos organofosforados e 4 piretróides em amostras de solo. O extrato contendo os analitos da etapa SLE/LTP foi empregado na etapa LDS/DLLME, substituindo o solvente dispersor dessa etapa. No processo optimizado, a acetonitrila foi selecionada como o solvente da etapa SLE/LTP (e também como solvente dispersor da etapa LDS/DLLME), e tolueno foi usado como o solvente de extração. Na validação do método, os valores das recuperações da extração ficaram na faixa de 87,6-102,5%, os limites de quantificação (LOQ) ficaram entre 3,0 e 10,0 g kg-1 e os valores de desvio padrão relativo (RSD) ficaram entre 5,6 e 19,2%. A técnica otimizada e validada foi aplicada em dois solos diferentes. Os valores de RSD obtidos ficaram na faixa de 1,9-20,1% (solo 1) e 1,4-20,5% (solo 2), e as recuperações ficaram entre 98,0-117,7% (solo 1) e 108,0-173,5% (solo 2), nos níveis de fortificação avaliados. A técnica hifenada se mostrou interessante por unir as vantagens de clean-up e simplicidade da técnica de extração SLE/LTP e da simplicidade, rapidez, baixo custo e alto fator de pré-concentração da técnica LDS / DLLME na determinação de agrotóxicos no solo.
Extraction procedures based on the principles of green chemistry have been under development since the 1990s, with miniaturization playing an important role. Here, a combination of solid-liquid extraction with low-temperature partitioning (SLE/LTP) and low-density solvent dispersive liquid-liquid microextraction (LDS/DLLME) techniques, coupled with gas chromatography with electron capture detection (GC/ECD), was used to determine two organophosphorus and four pyrethroid pesticides in soil samples. The extract containing the analytes from the SLE/LTP step was employed in the LDS/DLLME step, substituting the dispersive solvent. The SLE/LTP step and and LDS/DLLME step were optimized using factorial and univariate designs. In the optimized procedure, acetonitrile was selected as the SLE/LTP solvent (and also as DLLME dispersive solvent), and toluene was used as the extraction solvent. The extraction recoveries were in the range 87.6 - 102.5 %, and the limits of quantification (LOQ) were between 3.0 and 10.0 g kg-1. The relative standard deviation (RSD) values were between 5.6 and 19.2 %. The optimized and validated technique was applied to two different soil samples. The RSD values obtained were in the ranges 1.9-20.1% (Soil 1) and 1.4-20.5% (Soil 2), and the recoveries were 98.0 - 117.7 % (Soil 1) and 108.0 - 173.5% (Soil 2), at the fortification levels employed. The hyphenated method was interesting for coupling the advantages of clean-up and extraction technique (SLE/LTP) and of the simple, fast, cheap and high pre- concentration rate microextraction (LDS/DLLME) in determination of pesticides in soil.

Previous issue date: 2004-04-28This work intends to make one critical analysis of the discuss about science in the Fantástico television program. By the critical analysis perspective, the work tries to find signs that show the intention of both scientists and communicators discuss as well as the differences between the intention and the effective communication, as every communicative act is full of the conditions in that it was made and received. The work identifies the program as an enunciator of a discuss that is constructed by multiple voices that contribute to its construction. Since this role is identified, the analysis turns to the characteristics of the scientific information inside it.
Esse trabalho visa elaborar uma análise crítica do discurso sobre ciência presente no programa Fantástico de televisão. Dentro da perspectiva da análise crítica do discurso, busca-se encontrar marcas que indiquem a intencionalidade do discurso, tanto de cientistas como de comunicadores, bem como discrepâncias entre a intenção e a comunicação efetivamente realizada, na medida em que todo ato comunicativo é permeado também pelas condições em que foram gerados e recebidos. Dentro desse marco, o trabalho identifica o programa como enunciador de um discurso que se tece a partir das múltiplas vozes que contribuem para sua a realização. A partir da identificação desse papel, a análise se volta para as características da informação científica nele presente.

A pesquisa propôs o aproveitamento de resíduos sólidos da indústria regional de mineração e metalurgia do caulim e da bauxita em um compósito em estrutura sanduíche para aplicação como painel divisório de ambientes internos. A lâmina da estrutura sanduíche foi constituída de uma matriz de poliéster insaturada, tela dupla de juta, e 20% em massa do poliéster de resíduo de caulim e, o núcleo da estrutura, de poliuretano expansivo e lama vermelha (resíduo do processamento da bauxita para obtenção da alumina), em porcentagens 0% a 50% em massa da resina de PU (variando de 10 em 10%), totalizando 6 tratamentos diferentes. Os ensaios realizados foram os seguintes: de massa específica da lâmina da estrutura sanduíche (ASTM C271/271M – 11), de massa específica aparente (MEA) da estrutura sanduíche, de porosidade aparente (PA) da estrutura sanduíche, de tração na lâmina da estrutura (ASTM D5083-10), de tração transversal na estrutura sanduíche (ASTM C297/C297M - 04), de compressão longitudinal na estrutura sanduíche (ASTM C364/C364M–07), de compressão transversal na estrutura sanduíche (ASTM C365/C365M – 11a), de flexão por três pontos na estrutura sanduíche (ASTM D7250/D7250M – 06 e ASTM C393/C393M – 11), de impacto Charpy na estrutura sanduíche (ASTM D6110 – 10), de flamabilidade na lâmina e na estrutura sanduíche (UL 94 - 96) e de perda de transmissão sonora na estrutura sanduíche (ISO 140-3:1995 - E). Os resultados indicaram que a escolha de matrizes poliméricas foi apropriada para uma das características principais de uma estrutura sanduíche, que é a redução de peso, principalmente quanto à utilização da resina de poliuretano expansiva no núcleo. O incremento da lama vermelha não contribuiu para um aumento significativo da massa específica aparente da estrutura. O resíduo do caulim aumentou a resistência à tração na lâmina. O incremento da lama vermelha diminuiu as resistências à tração transversal, à flexão e ao impacto na estrutura. Quanto às compressões longitudinal e transversal na estrutura, o incremento na concentração de lama vermelha não influenciou nesses resultados, somente o acréscimo da lama vermelha diminuiu a resistência da estrutura sanduíche no primeiro ensaio e aumentou a resistência da mesma no segundo ensaio. A alta flamabilidade do PU foi retardada por ter sido enclausurado pelas lâminas de poliéster e resíduo de caulim, comprovando que esse resíduo apresenta propriedade de retardante de chama e quanto ao ensaio de perda de transmissão acústica, o incremento de lama vermelha aumentou a perda até a concentração de 20%, depois, ficou estabilizada em 25 dB (STC) até os 50% de lama. O material, como um todo, apresentou característica de uma estrutura sanduíche, com um núcleo de baixa massa específica, contribuindo para a redução de peso da estrutura e de lâminas de maiores resistências, que proporcionaram ao compósito a funcionalidade estrutural desejada de um painel divisório de ambientes internos.
The rechearch proposed to use solid wastes from kaolin and bauxite mining and metallurgical regional industries in a composite of sandwich structure to apply as internal divider panel environments. The blade was of unsaturated polyester matrix, double jute fabric and, kaolin waste (20 wt% polyester) and, the core, of polyurethane expansive and red mud (bauxite waste at process to get alumina), from 0 to 50 wt% PU (increasing by 10 to 10 wt%), in a total of 6 different treatments). The tests carried out were: blade density (ASTM C271/271M – 11), sandwich structure bulk density apparent, sandwich structure porosity, tensile test on the blade (ASTM D5083-10), flatwise tensile test on sandwich structure (ASTM C297/C297M - 04), edgewise compressive test on sandwich structure (ASTM C364/C364M–07), flatwise compressive test on sandwich structure (ASTM C297/C297M - 04), 3-point flexural test on sandwich structure (ASTM D7250/D7250M – 06 e ASTM C393/C393M – 11), Charpy impact test on sandwich structure (ASTM D6110 – 10), flammability test on blade and on sandwich structure (UL 94 - 96) and sound transmission loss test on sandwich structure (ISO 140-3:1995 - E). The results indicated that the choise of polymeric matrices was suitable to reduce weight of such structure mainly the use of a PU expansive. Increasing red mud not contributed to significant increase of sandwich structure bulk density apparent. Kaolin waste reinforcement increased resistance to blade on tensile test. Red mud reinforcement reduced sandwich structure resistance on flatwise tensile, flexural and impact tests. Increasing of red mud didn’t influenced sandwich structure edgewise compressive and flatwise compressive tests but, but it´s use at this sandwich structure, decreased their resistance at the first test and increased at the second test. The PU high flammability was delayed for being cloistered by two blades of polyester and kaolin, proving flame retardant property of kaolin waste. And about sound transmission loss test, the increase of red mud increased that until 20% concentration, after this, stabilized at 25 dB (STC) until 50% red mud. The composite, as a whole, presented feature of a sandwich structure, with a low density core, contributing to reduce structure weight and with higher resistant blades, providing it the desired structural feature to be a divider indoor panel.

This study arises from the attempt to collaborate with the improvement of living conditions of imprisoned black women. What are the possibilities of emancipatory actions based on educational processes that are based on the articulation of thematic axis of Human Rights and Affirmative Action facing the vulnerabilities of the condition of imprisoned black women? According to the raised profile, the female prison population is characterized as black or mixed-race, young, single mother and the vast majority arrested for involvement in drug trafficking. Thus, we aim to develop an understanding that can contribute to the formulation of actions for this specific population, reflecting the new paths enabling the organization of subjects of rights and their struggles. To achieve this goal we have as a methodology the survey and analysis of the relevant bibliography. The construction of the study’s objective is referenced in some theorists and the postcolonial perspective that addresses themes that pervade and articulate the interfaces between race relations, gender and human rights: Franz Fanon, Boaventura de Souza Santos, Kabenguele Munanga Michel Wieviorka, Michel Foucault, Paulo Freire, among others. The research results show that the absence of works that address the specificities of black women and the racism present in the logic of the prison system, as well as proposals for affirmative action will undermine the chances of emancipatory educational practices that address the vulnerabilities of the condition of imprisoned black women. We emphasize that the cyclical problems of the prison system can only be addressed properly through actions based on the real reasons for mass incarceration of the black, poor and peripheral population.
Essa pesquisa nasce da tentativa de colaborar com a melhoria das condições de vida das mulheres negras presidiárias. Quais são as possibilidades de ações emancipatórias fundamentadas nos processos educativos que tenham como base a articulação dos eixos temáticos dos Direitos Humanos e das Ações Afirmativas diante das vulnerabilidades da condição das Mulheres Negras Presidiárias? Segundo o perfil levantado, a população carcerária feminina é caracterizada como preta ou parda, jovem, mãe solteira e na grande maioria presa por envolvimento com tráfico de drogas. Sendo assim, visamos desenvolver uma compreensão que possa contribuir com a formulação de ações para essa população específica, refletindo os novos caminhos que possibilitem a organização dos sujeitos de direitos e suas lutas. Para alcançar esse objetivo temos como metodologia o levantamento e análise dos conteúdos dos materiais bibliográficos considerados relevantes ao tema. A construção do objeto de investigação está referenciada em alguns teóricos e na perspectiva pós-colonial que abordam temáticas que perpassam e articulam as interfaces entre as relações raciais, de gênero e de direitos humanos: Franz Fanon, Boaventura de Souza Santos, Kabenguele Munanga, Michel Wieviorka, Michel Foucault, Paulo Freire, entre outros. Os resultados da pesquisa demonstram que as ausências de trabalhos que abordem as especificidades das mulheres negras e do racismo presentes na lógica do sistema prisional, assim como de propostas de ações afirmativas comprometem as possibilidades de práticas educativas emancipatórias que enfrentem as vulnerabilidades da condição das Mulheres Negras Presidiárias. Salientamos que os problemas cíclicos do sistema carcerário só podem ser enfrentados devidamente por intermédio de ações fundamentadas nos reais motivos do encarceramento em massa da população preta, pobre e periférica.

Seit Beginn der 80er Jahre erfreuen sich zwischenbetriebliche Kooperationen wachsender Beliebtheit. Mit den virtuellen Unternehmen ist Anfang der 90er Jahre eine neue interessante Variante hinzugekommen. In virtuellen Unternehmen (vgl. Hess 1999) arbeitet eine größere Zahl von Unternehmen auf partnerschaftlicher Basis ohne Aufgabe der rechtlichen Selbständigkeit langfristig zusammen. Aus diesem Pool von Unternehmen werden auftragsbezogene Teams gebildet. Ebenfalls charakteristisch für virtuelle Unternehmen ist der massive Einsatz von Informations- und Kommunikationssystemen (IuK-Systemen) für Koordination und Kooperation. Beispiele für virtuelle Unternehmen finden sich vorwiegend - aber keineswegs ausschließlich - im Dienstleistungssektor, insbesondere in der Informatik und der Beratung (vgl. Mertens/Griese/Ehrenberg 1998). [... aus dem Text]

Full textAbstract:
Die Entwicklung der Neuen Medien verändert die Art der Zusammenarbeit von Gemeinschaften. Dies gilt in entscheidendem Maße auch für den Wissensaustausch der weltweiten akademischen Gemeinschaft. Das Institut für Medien- und Kommunikationsmanagement der Universität St. Gallen erforscht und fördert diese Veränderungen im Rahmen des Projektes NetAcademy.
Akademische Gemeinschaften benötigen Medien für die Akkumulation, Dissemination und Diskussion von Wissen. Hierbei bedienen sie sich der Möglichkeiten und Vorteile sowohl traditioneller als auch der Neuen Medien. Die Entwicklung der Informationstechnologie beeinflußt alle Aspekte akademischer Aktivitäten, ob es sich hierbei um Forschung, Lehre oder um die Publikation der wissenschaftlichen Diskussion handelt. Die Frage, wer Verleger und Publizist welcher Inhalte wird, hat sich mit den Möglichkeiten, die das Medium Internet bietet, stark verändert.
Bislang wurde das Publizieren akademischer Inhalte von professionellen Verlagen dominiert. Diese Verantwortlichkeiten verschieben sich nun zunehmend auf die akademischen Institutionen selbst, welche die Möglichkeiten der Neuen Medien im Publikationsprozeß erkannt haben und nutzen. Kommerzielle Marktakteure werden durch diese Entwicklung eine geringere Rolle spielen als bisher. Die ursprüngliche Idee der akademischen Kommunikation kann in umfassenderer Weise über die Neuen Medien realisiert werden. Die Entwicklung wissenschaftlicher Gemeinschaften wird somit bekräftigt und vorangetrieben.
Ein neues System der akademischen Kommunikation, das auf elektronischen Systemen und Netzwerken basiert, erfordert nicht nur neue konzeptionelle Modelle für wissenschaftliches Publizieren und Datenhaltung, sondern auch neue interpersonale und institutioneile Praktiken und Einstellungen. Noch fehlt es vielfach an gemeinsamen Plattformen im Medium Internet, die eine hohe Qualität sichern und den zentralen Anforderungen an die Darstellung akademischer Inhalte - im vorliegenden Papier als 3R (Retrieval, Rating, Reliability) [Schmid-Isler/Selz/Wittig 98] bezeichnet - gerecht werden. Die vorliegende Arbeit wird sich vorrangig mit dem Aspekt der Qualitätssicherung - einem der zentralen Ziele der NetAcademy - und damit der Frage des Rating bzw. Reviewing akademischer Inhalte befassen.

Full textAbstract:
Conodonts are important biostratigraphic tools for the delineation and calibration of the geochronological boundaries within the Carboniferous and used generally as stage-boundary markers for the Lower Carboniferous (Mississippian). The studied successions in the Central and Eastern Taurides were mainly deposited in a shallow marine environment during the Carboniferous time and they comprise less abundant and diversified conodont fauna. The conodont fauna represented by twenty-four species belonging to ten genera have been described from the studied sections (ASAAO
BSE and HB) in the Taurides (Turkey). Regarding the first occurrences and last occurrences of biostratigraphically significant species within these sections, the following zones have been established across the Lower Carboniferous successions: (1) Polygnathus inornatus Zone (Hastarian-Lower Tournaisian)
(2) Gnathodus cuneiformis &ndash
Polygnathus communis communis Zone (Ivorian-Upper Tournaisian)
(3) Polygnathus mehli mehli Zone (Ivorian-Upper Tournaisian)
(4) Gnathodus girtyi girtyi Zone (Brigantian-Upper Visean)
(5) Gnathodus girtyi simplex Zone (Pendelian-Lower Serpukhovian)
(6) Rhachistognathus muricatus Zone (Zapaltyubinsky-Upper Serpukhovian) and (7) Declinognathodus inaequalis - Declinognathodus noduliferus Zone (Bogdanovsky-Lower Bashkirian). Based on the recovered conodont assemblages, Visean - Serpukhovian boundary has been recognized by the first occurrence of Gnathodus girtyi simplex and the Mid-Carboniferous boundary is delineated by the first occurrence of Declinognathodus inaequalis, which is an index taxon for the basal part of the Bashkirian. Based on the microfacies studies it can be concluded that conodont elements essentially obtained from the crinoidal bioclastic packstone-grainstone, crinoidal packstone-grainstone, coated bioclastic grainstone, intraclastic grainstone and spiculite packstone facies in the studied sections. It can be concluded that that the occurrence of abundant crinoids are indicative criteria for the presence of conodonts. Additionally, geometric morphometric analyses of biostratigraphically important genus, Gnathodus, on the basis of data available in the literature emphasize the importance of numerical taxonomy and reveal that taxonomic revision of this genus is needed.

"Neben „klassischen“ virtuellen Gemeinschaften, die einen gemeinsamen Netzort für die Interaktion benutzen und die auf technischer Ebene vornehmlich durch den Einsatz von Client-Server-Architekturen gekennzeichnet sind, lassen sich Gemeinschaftsformen identifizieren, deren Ursprung in vollkommen dezentralen Peer-to-Peer (P2P)-Netzen liegt. Diese P2P-Gemeinschaften haben in einigen Anwendungsgebieten wie dem Filesharing großen Erfolg [SF02]."

Full textAbstract:
Die Wirtschaftskrise der Jahre 2007 bis 2010 ist an der deutschen Industrie nicht spurlos vorüber gegangen. Neben den drastischen Einbrüchen in Absatz und Umsatz, war sie aber auch dadurch gekennzeichnet, dass die betroffenen Unternehmen sehr verhalten mit Mitarbeiterentlassungen reagierten. Vielmehr haben die Organisationen an ihrem Stammpersonal festgehalten, um sich deren Know-how zu sichern. Infolge der Krise war der Tenor der Wirtschaftsteilnehmer, dass aufgrund der weltweiten Vernetzungen, sie den volatilen Konjunkturverläufen auch zukünftig ausgesetzt sein werden. Die Unternehmen müssen deswegen lernen mit ihnen umzugehen.
Dabei rücken immer mehr neue Technologien in den Fokus, die innerhalb des Unternehmens, die Zusammenarbeit der Mitarbeiter verbessern sollen. Das Thema ‚Enterprise 2.0‘ nimmt zunehmend Form an, die Vorstellungen und Umsetzungen werden konkreter. ‚Enterprise 2.0‘ ist dadurch gekennzeichnet, dass sowohl Mitarbeiter als auch bestehende Unternehmensprozesse und -kommunikation vor neue Herausforderungen gestellt werden. Der Autor des Beitrags nimmt dies zum Anlass, in seinem Promotionsvorhaben den Fragestellungen nachzugehen, ob für den Einsatz von Web 2.0-Technologien, den Medien, die bei Enterprise 2.0 Verwendung finden, eine neue Generation Mitarbeiter notwendig ist.

"Im Zeitalter von Internet und elektronischen Medien und Reform didaktischer Prinzipien sind die althergebrachten Formen des Lehrens und Lernens neu zu überdenken. Gerade an den Hochschulen müssen Potenziale effektiven und realitätsnahen Lernens geschaffen werden, um die Studierenden auf die veränderte Berufswelt vorbereiten zu können und sie zu einem „lebenslangen Lernen“ zu befähigen. Daher ist es geboten, die traditionellen Lehr- und Lernszenarien, dominiert von Frontalunterricht und Dozentenzentriertheit, die an deutschen Hochschulen überwiegen, in Frage zu stellen und neue, kooperative und internetbasierte Formen zu entwickeln."

Zusammenfassung:
"In diesem Artikel soll der Einsatz von Distributed Virtual Environments (DVE) zur Bildung von Virtual Communities (VC) für kommerzielle Interessen untersucht werden. Nach der Charakterisierung von VC und DVE wird deren Symbiose zum Zweck der Kundengewinnung und -bindung im Consumer-Bereich untersucht. Dabei wird eine kritische Bewertung erster Prototypen und die Analyse der damit verbundenen technologischen, psychologisch-soziologischen und marketing-strategischen Probleme vorgenommen. Auf dieser Basis erfolgt abschließend die Diskussion eines Vorgehensmodells für den Aufbau DVE-basierter Gemeinschaften zur kommerziellen Nutzung und die Spezifikation eines Anforderungskataloges für erfolgreiche DVE in diesem Sektor."

Full textAbstract:
Das Interesse an Untersuchungen über Erfolgsfaktoren von Projekten im Umfeld digitaler Produktionen1 rührt auch daher, dass immer noch viele Projekte in Schieflage geraten oder gar scheitern. Die Gründe hierfür liegen meist im mangelhaften Management dieser Projekte. Hier besteht Bedarf nach Fachkompetenz der bspw. durch die Inanspruchnahme von Projekt-Coaching gedeckt werden kann. Projekt-Coaching unterstützt die Projektbeteiligten bei der Bewältigung von Projektmanagementaufgaben durch eine fachliche und persönliche Beratung. Die Zusammenarbeit zwischen dem Coach und der zu beratenden Person (Coachee) beruht auf dem zu Grunde liegenden Vertrauensverhältnis und dem intensiven persönlichen Kontakt. Die Interaktion im Coaching-Prozess ist somit mit einem hohen Kommunikations-, Koordinations- und Zusammenarbeitsaufwand verbunden, was jedoch bei zeitkritischen Projekten häufig nicht durchführbar ist. Oftmals fehlt vielen Unternehmen mit Coaching-Bedarf auch ein direkter Zugriff auf einen Pool geeigneter Projekt-Coaches. Findet ein Coaching-Prozess statt, ist dieser mit mehreren persönlichen Gesprächen verbunden, die meist in Form von Präsenzterminen stattfinden. Diese müssen geplant, koordiniert, vorbereitet, durchgeführt und nachbereitet werden, was vor allem bei örtlich verteilten Akteuren einen hohen organisatorischen Aufwand bedeutet.

Full textAbstract:
The aim of this study is to delineate the Campanian-Maastrichtian boundary by using planktonic foraminifers. In this manner, Kokaksu Section (Bartin, NW Anatolia) was selected and the Akveren Formation, characterized by a calciturbiditic-clayey limestone and marl intercalation of Campanian-Maastrichtian age, was examined. 59 samples were emphasized for position of boundary.
Late Campanian-Maastrichtian planktonic foraminifers were studied in thin section and by washed samples. Two different biostratigraphical frameworks have been established. Globotruncanid zonation consists of Campanian Globotruncana aegyptiaca Zone, Upper Campanian-Middle Maastrichtian Gansserina gansseri Zone and Upper Maastrichtian Abathomphalus mayaroensis Zone, whereas heterohelicids biozonation includes Campanian Pseudotextularia elegans Zone, Lower Maastrichtian Planoglobulina acervuloinides Zone, Middle Maastrichtian Racemiguembelina fructicosa Zone and Upper Maastrichtian Pseudoguembelina hariensis Zone. Campanian-Maastrichtian boundary was determined as the boundary between Pseudotextularia elegans and Planoglobulina acervuloinides zones and Cretaceous-Tertiary boundary was designated by total disappearance of Late Cretaceous forms. Heterohelicid biozonation has been established in this study for the first time in Turkey.
Collecting 300 individuals from each sample, diversity and abundance of assemblages were analyzed in terms of genus and species. ir evaluation of are important in observation of evolutionary trends and ecological changes. Moreover, evolution of different morphotypes is important in this evaluation. Such a study is new in Turkey in terms of examination of responses of planktonic foraminifers to environmental changes.
Taxonomic framework has been constructed to define each species and differences of comparable forms have been discussed. Both scanning electron microscope (SEM) photographs and thin section photographs were used in order to show se distinctions.
